refrigeration and food retailing applications.
Reference: For details please see EIM data sheet.
Technical specifications
Supply voltage 24 V AC / DC (+ 15%), 50 / 60 Hz, 15 VA / 8 W, Class II isolation
Idle
Power consumption
Input signals For the EMC compliance, sensor cable length must be < 3 m / 118 in. For longer sensor cable, a ferrite bead should be used.

Installation warnings
Colibri®
- Recommended mounting position: vertical
- Installation must comply with local standards and legislation
- Before working on the electrical connections, disconnect the device from the main power supply
- Before carrying out any maintenance operations on the device, disconnect all electrical connections
- For safety reasons the appliance must be fitted inside an electrical panel with no live parts accessible
- Do not expose the device to continuous water sprays or to a relative humidity greater than 90%
- Avoid exposure to corrosive or pollutant gases, natural elements, environments where explosives or mixes of flammable gases are present, dust, strong vibrations or shock, large and rapid fluctuations in ambient temperature that might cause condensation in combination with high humidity, strong magnetic and/or radio interference (e.g. transmitting antennae).
- When connecting loads be aware of the maximum current for each relay and connector
- Use cable ends suitable for the corresponding connectors. After tightening connector screws, tug the cables gently to check their tightness.
- Use appropriate data communication cables. Refer to the EIM data sheet for the kind of cable to be used and setup recommendations.
- Minimize the length of probe and digital input cables as much as possible, and avoid spiral routes around power devices. Separate from inductive loads and power cables to avoid possible electromagnetic noises.
- Avoid touching or nearly touching the electronic components fitted on the board to avoid electrostatic discharges.

Note:
• If two EIMs are connected remember to remove the addressing jumper on one of the EIMs
• MODBUS transmission lines usually require termination resistors, especially for longer cable lengths
